The "bourgeois establishment" probably didn't/doesn't like a whole heap of Stalinist bureaucrats because they saw them as being in some sense threatening to their interests. But so what, frankly?
We don't base our assessment on political figures solely on their relationship to "the establishment." We base it on their relationship to the workers' movement, domestically and internationally, and class struggle.
Again, it's a question of being honest and telling the truth. When the hegemonic voices on the left were creating a clamour of disgusting sycophancy for Galloway (which has now, tragically and predictably, come back to bite them), those of us who had a different - more sober, critical, realistic - assessment of Galloway and his role had a responsibility to make that heard, not to subsume ourselves into a chorus of cheers (while maybe whispering a few criticisms at the back).
